With all the technology available to us in recent times, it’s not hard to build a safety device for women which will not only generate an emergency alarm but also send a message to your friends, family, or concerned person. Here we will build a band that can be worn by women, using which they can inform police or anyone, using SOS emergency SMS along with the current location. Using this information, the police will be able to save the victim from the location. For this, here we are using an Arduino which can be interfaced with GSM and GPS module for sending SMS alerts and getting the location coordinates. We have also used an RF Transmitter and receiver module for wireless communication between the Band and Receiving device with GPS/GSM.
Here we are using the NEO6M GPS module. The NEO-6M GPS module is a popular GPS receiver with a built-in ceramic antenna, which provides a strong satellite search capability. This receiver has the ability to sense locations and track up to 22 satellites and identifies locations anywhere in the world. With the on-board signal indicator, we can monitor the network status of the module. It has a data backup battery so that the module can save the data when the main power is shut down accidentally.
